Hmmmm.... I might agree with you if you're referring to a temporary situation. That simply sounds like clumsy management on Delta's part.

However, I think that the original contention was that one of the Majors, as a matter of corporate policy, published a schedule that could never be fully executed given the airline's staffing and/or equipment profile. I strongly doubt this.

The Regionals and Air Taxis are another case altogether. They are not above cancelling flights due to low loads.
